Specification of Letters Patent.

Application filed .Tune 29, 1914. Serial No. 847,966.

Be it known that I, WALTER J. MEILUK, a subject ofthe Czar of Rpssia, residing at Hamilton, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Reciprocating Fluid-Motors, of which the following is a specification.

This'invention relates to new and useful improvements in a reciprocating fluid motor.

The primary object of the invention is the provision of a reciprocating motor adapted for actuation by any desired fluid and especially serviceable as a water motor and is capable of continuous operation under a constant fluid pressure.

A further object of the invention is to provide a power imparting reciprocating piston which is driven in alternating opposite directions by means of fluid pressure automatically governed for regulating its admission and exit to the piston chamber.

A still further object is toprovide in connection with a fluid driven reciprocating piston, an automatipally operated oscillating valve and opera ing means for regulat ing the alternations of supply and exhaust of the motive fluid.

' others that will appear as the nature of the With these general objects in view and invention is better understood, the same.con-- sists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed outin the appended claims.

In the drawings forming a part of this application andin which like designating characters refer to corresponding parts throughout the several views, a perspective view of the device. Fig. 2 is a top plan view thereof with one end of the piston broken away. Fig. 3 is a side elevation thereof. Fig. 4 is a top plan view with a portion of the cylinder broken away and illustrating the piston in the reverse position from that shown in Fig.2. Fig. 5 is a vertical transverse central sectional view of F1g. 6 1s a perspectlve view of the device. the fingered arm detached of the valve mechanism. Fig. "7 is a perspect ve view of the piston slide rod detached. Fig. 8 is a perspective view of the valve stem detached. Fig. 9 is a perspective view of the valve plug detached. Fig. 10 isa central trans-1 Figure. 1 is verse sectional view through the valve showing the valve port connecting between the fluld inlet and the piston pipe. Fig. 11 is a horizontal transverse sectional view thereof,,and Fig. 12 is a horizontalsectional view of the valve with the plug and its ports positioned opposite to that illustrated in Figs. 10 and. 1

Referring more in detail to the drawings, 1t is designed to mount the present construction of reciprocating motor upon a table or base 10. A hollow piston 11 has its opposite ends mounted for reciprocation within oppositely positioned cylinders 12, each having a piston chamber 13 therein and in alinement with each other.

A valve cage 14 of cylindrical form is positioned at one side of the piston and is pro vided with a cap 15 while pipes 16 connect the opposite outer ends of the cylinders 12 with branch pipes 17, which latter pipes a pass through the cage 14 and are tapped into the valve casing 18 arrangcdwithin the cage 14.

The valve casing 18 is provided with a slightly tapered central bore 19 having an oscillating valve plug 20 mounted therein and adapted to be turned by means of the arm 21 which is secured to the top of the valve plug.

The fluid for operating the motor is conducted to the angular port 22 of the valve. plug by pipe 23 upon the motor base 10, which pipe communicates through the pipe 24 beneath the base with the connecting collar 25 within which the extension pipe 26 extends for rotation, said pipe 26 being carried by the valve plug and being in communication with the plug bore 22, as best illustrated in Fig. 10. A retaining plate 27 is secured to the lower surface of the turn to the bore 22 and from whence it passes through the left hand pipe 16 to the corresponding end chamber of the piston cyhn- .der and may then operate upon the left end of the piston for forcing the same outwardly of the cylinder towaqd the right. In this position of the valve mechanism 1t w1ll be seen also that the right hand pipe 16 allows 0 ,Y

the fluid to exhaust from the right hand cylinder 12 and to communicate with the right hand pipe 17 and thence to the right hand exhaust pipe 29 which is threaded into one of the oppositeopenings 30 ofthe valve The piston 11 is provided with a collar 32 having a connecting rod 33 which is adapted to be coupled up to any desired mechanism to be operated by the motor. A frame 34 is also carried by the piston collar 32 and rigidly supports arod 35 which reciprocates with'the piston and is slidably journaled in the rearwardly projecting arms 36 of the valve cage 14; i

An arm 37 is pivoted centrally to a'strap 38 which traverses the cage 14 and has downwardly projecting spaced'fingers 3? for freely receiving the arm 21 therebetwe'en at the exterior of the cage 14, it being noted that the arm 21 projects throu h the front slot 40 of the cage while the ar 37 rojects through a similar slot 41 positione thereabove in the front wall of the said cage.

A connection is provided between the rod 335 and the valve actuating arm-37 which 0 consists of a-link 42 pivotally connected to the rod 35 substantially centrally thereof and having a coil spring 43 secured between the free end of said link and the actuating arm 37 the said link 42 entering the valve cagethrough the rear slot 44. The complete operation of the device it is thought will be apparent from the above detailed description thereof. The admission of fluid such as water is adapted to remain under constant pressuredn the supply pipe 24 which at all times communicates with the valve plug bore 22 and is adapted to be automatically connected with the opposite cyl I inder supply pipe "16 alternately by means of the oscillating valve actuating means. It will be apparent that with the elements posi I tioned'as illustrated in Figs. 1 and 2, that the-piston will be forced toward the right v as theleft hand'chamber 13 is supplied with the'fluid under pressure and that the right I handcha'mber being in communication with --the .right hand exhaust pipe 30, the fluid f is within said right hand chamber will be exh'auslted by the force of-t he incoming piston 11: Such, movement of the piston carries operation being a forcible snapping ofsaid the rod 35 with its link 42 toward the right, which link having resilient connection with the arm 37, will be placed under increased -tension until the link passes the center of the valve plug above the same and whereupon the continued movement of the link toward the right will exert its force upon thearm 37 to force such arm toward the right to the position illustrated in Fig. 4, the

armfrom one position to the other after the link-has passed. the line of center of the plug. It will be of course evident that the engagement of the'fingers of the arm 37 with the arm 21 necessarily moves the arm 2l'whenever the arm 37 is actuated and by all of which-mechanism, the reciprocation of the rod 35 upon the movements of the piston automatically reverse the fluid valve for actuating the piston in its opposite reciprocations, it being also noted thatthe reversal of the valve is'notcompletely effected until each reciprocation of the piston is substantially completed. By all of this arrangement there is provided a motor in which any desired fluid may be supplied to the valve port extension-26 under a substantially uniform pressure and. a continuous operation of the piston-is thereby eiiected while shown and described are What are believed tobe preferable embodiments thereof, it is nevertheless to be understood that minor 10 0 changes may be made in the form, proportion and details of construction without departing from the spirit and scope of the invention as set forth in the appended claims.
